Abstract

PROBLEM TO BE SOLVED: To efficiently suck dust under any floor surface condition by detecting electric currents of a motor-driven fan and a brush-driven motor and controlling the input to the motor-driven fan in accordance with the detected values. SOLUTION: When the electric current input in a main body motor 11 is detected by means of a motor electric current detecting part 6 and the electric current input in a brush-driven motor 13 is detected by means of a brush-driven motor electric current detecting part 21, the electric current input in the main body motor 11 is controlled depending on the condition whether the brush-driven motor 13 is driven, namely, whether or not the electric current is detected by the brush-driven motor electric current detecting part 21 and the suction force of the motor-driven fan is controlled thereby. It is possible thereby to prevent fibers of a carpet from being entangled on a power brush and to prevent a suction part from hardly moving. Therefore, it is possible to suck efficiently dust under any floor surface condition.

Description of the Related Art Conventionally, an electric vacuum cleaner (hereinafter, simply referred to as "vacuum cleaner") characterized by detecting a current flowing through an electric blower and controlling an input to the electric blower based on the detected value is, for example, a special one. It is described in Kaihei 5-23273. In the vacuum cleaner described in the above publication, even if the current flowing through the electric blower is increased in order to increase the amount of suction air for dust and the like, the suction work rate (that is, the suction efficiency of dust and the like) is improved when the current exceeds a predetermined value. By not doing so, the current flowing through the electric blower is limited so that the current flowing through the electric blower does not exceed the predetermined value.

分に吸込むことができないことがある。However, in such a conventional vacuum cleaner, since the current value of the electric blower is detected and only the input of the electric blower is controlled by the detected value, the suction for the floor is reduced. If the drive motor for the power brush of the tool is forgotten to be operated, the suction force may be insufficient when cleaning a floor surface such as a carpet having a high suction resistance, and dust may not be sufficiently sucked.

いた。Further, since the input of the electric blower is controlled irrespective of the rotating condition of the power brush provided in the floor suction port, the rotating force of the power brush can be controlled according to the condition of the floor surface. However, for example, in the case of a long-haired carpet, the fibers of the carpet were stuck to the carpet, resulting in poor operability.

装置とを設けている。BEST MODE FOR CARRYING OUT THE INVENTION A vacuum cleaner according to the present invention has a main body of a cleaner having an electric blower built therein, a suction port provided in the main body of the cleaner and a rotary brush, and a rotary brush and the rotary brush. A floor inlet provided with a brush drive motor to be driven, a current detection device for detecting currents of the electric blower and the brush drive motor, and control of input to the electric blower corresponding to the detected value.

吸いとるようにする。For example, if the brush drive motor of the rotary brush, which is the power brush of the floor suction tool, is forgotten to move,
The detection value detected by the current detection device becomes small as much as no current is input to the brush drive motor. Therefore, when the detected value becomes small, the electric current value input to the electric blower from the electric blower control device becomes large so that the suction force of the vacuum cleaner is increased and the dust on the floor surface is efficiently sucked. .

防止する。Further, when the brush drive motor of the rotary brush is operated, the detection value detected by the current detection device becomes large because the currents of both the electric blower and the brush drive motor are detected. Therefore, when the detected value becomes large, the current value input to the electric blower from the electric blower controller becomes smaller than when the brush drive motor is forgotten to be operated, and the suction force of the cleaner is made smaller. Prevents the fibers of the carpet from being entangled in the rotating brush that occurs when the carpet is used in long-haired carpets.

る。In the present invention, when the voltage value of the sawtooth wave generated by the waveform generator 3 is increased by an arbitrary value, for example, the sawtooth wave shown in FIGS. 4 (a) and 5 (a) is used. The sawtooth wave generated by the waveform generator 3 can be set to change in the range of 1 to 6 V by increasing the amount by 1 V, and the suction force of the electric blower can be controlled according to the setting. it can. Therefore, when the brush drive motor is stopped by this control method, the suction force of the electric blower becomes large. Conversely, when the brush drive motor is operating, the suction force of the electric blower is small, so even when using an electric blower for a carpet with long hair, the fibers of the carpet are entangled and sucked in the power brush. It is possible to prevent the portion 17 from becoming difficult to move.
